A piano hinge is also called a continuous hinge, and is a popular hinge to use on side doors and other small doors. This tutorial shows you the proper method of installing a piano hinge on your current project. Besides the door and the hinge, you will also need some basic hardware: a drill and some screws, as well as a chisel to carve out an inset for the hinge to rest.
